Charles Spurgeon Commentary John 12:35-36

"Jesus therefore said unto them, Yet a little while is the light among you. Walk while ye have the light, that darkness overtake you not: and he that walketh in the darkness knoweth not whither he goeth. While ye have the light, believe on the light, that ye may become sons of light. These things spake Jesus, and he departed and hid himself from them." — John 12:35-36 (ASV)

Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you; for he that walketh in darkness knoweth not whither he goeth. While ye have light, believe in the light, that ye may be the children of light.

These things spake Jesus, and departed, and did hide himself from them.

When people determine to reject Christ, he leaves them; why should he remain where he is rejected? He departed, and did hide himself.
